Field Jacking Test of Steel Tubes with Flange Slabs in a Layer of Sand
(1 College of Resource and Civil Engineering, Northeastern University, Shenyang 110819; 2 The Fifth Construction Co. Ltd. of China Railway Fourth Group, Jiujiang 332005)
Abstract The STS (Steel Tube Slab) curtain method, which consists of a load supporting structure formed by the
coupling of steel tubes with concrete, flange slabs and bolts, is a new construction method used in the construction of super-shallow subway stations. Based on a subway station in Shenyang, this paper studies the construction difficulties and rectification techniques in the jacking construction of a steel tube with flange slabs, and presents relevant solutions and control measures, thereby providing a reference for the popularization of the STS curtain method.
